In a candid interview published today in Brain Medicine by Genomic Press, Professor Philip Hyland shares his transformative journey from personal anxiety struggles to becoming a global leader in posttraumatic stress disorder (PTSD) research—one that has reshaped how clinicians worldwide treat trauma survivors.
His groundbreaking work on Complex PTSD directly influenced updates to the World Health Organization’s diagnostic criteria, marking a pivotal shift in trauma care.
Hyland’s career in psychology was sparked by a personal crisis in his late teens and early twenties, during which he grappled with unexplained anxiety and depression.
“I wanted to understand why I felt so unhappy,” he explains, a drive that led him to abandon childhood interests in physics and astronomy for psychology—a field he notes “didn’t require brilliance at math.”
This personal connection to mental health struggles fueled his mission to center patient experiences in trauma assessment and treatment.
A key pillar of his work is challenging traditional clinical practices: Hyland advocates for prioritizing self-reported symptoms over clinician judgments. “If you want to know what someone is experiencing, ask them,” he asserts, a stance that defied decades of tradition.
This patient-centered approach led to the creation of the International Trauma Questionnaire, now used globally to improve PTSD assessment and inform treatment strategies.
Beyond PTSD, Hyland’s research expands into underrecognized areas of suffering. His recent work validated that prolonged grief disorder can develop after a pet’s death—despite current diagnostic manuals ignoring this possibility. “That irritated me, so I had to investigate,” he says, reflecting his drive to address gaps in mental health understanding. He also co-leads Ireland’s first major sexual violence prevalence study since 2002, merging scientific rigor with social advocacy.
While Hyland credits “extraordinary luck” for his success—including collaborations with mentor Professor Mark Shevlin and his role at Maynooth University—his impact is rooted in rigorous science. With nearly 20,000 citations across 340+ publications, the 2023 Early Career Achievement Award winner now serves as Deputy Statistical Editor for the Journal of Traumatic Stress and chairs the International Trauma Consortium.
When asked about his goals, Hyland prioritizes “truth over recognition.” “I do work that matters, not for impact,” he says, emphasizing scientific integrity amid concerns about activism influencing research. For trauma survivors and clinicians alike, his work stands as a testament to how personal insight and scientific rigor can redefine PTSD treatment for the better.
